We all know not to leave a dog in a car on a hot day, but pet owners might also need to take measures to keep Fido from overheating on blazing summer days on the trail or at the campsite. Dogs can’t sweat, of course, so one option (besides water, plenty of water), is a cooling vest. Dip the vest in cold water, wring it out, put it on your dog’s torso and let the “evaporative cooling effect” keep the body temperature from overheating.

If you aren’t impressed, awed and a little freaked out by this you-are-there Google street view of sheer faces of El Capitan, then you must not have a pulse. Tommy Caldwell, Lynn Hill and Sacramento-native Alex Honnold are your tour guides. Almost as impressive is how Google was able to capture the images, which is explained on the site.
